Brick Masonry

The art of construction in bricks is called brick masonry; Bricks are laid with cement mortar or lime mortar. In ordinary and inferior quality of works, mud mortar is also used. Brick masonry laid with cement mortar is stronger and more durable than that laid, with lime mortar. But lime mortar is very commonly used due to its low cost.

Bricks are made in a range of varieties, each intended for a specific purpose, but all are created from some combination of sand, water, clay, and heat. Building brick, or common brick, is used in construction and is often “cored” with two rows of holes to save material and reduce weight. Face brick is chosen for visible surfaces or exposed walls and comes in different colors, sizes, and shapes. Firebrick is made with special clay to offer additional heat resistance in fireplaces or boiler rooms. Glazed brick is coated on one surface with a ceramic finish that is sanitary and easy to clean, making it popular in hospitals and laboratories.
